If you love colour but are sometimes unsure of what mixes with what and how complementary colours work then you need a Colour Wheel. This wheel illustrates colour relationships as well as showing you how what results you will get by mixing colours together. And as a bonus we are including the Pocket Guide to Mixing Colour which will help with colour harmonies. Wheel measure approx 13.3cm (5.25")in diameter. The Pocket guide, when folded, measures 13cm x 7.7cm (5" x3").
